Answer:
θ = 12.60°
Explanation:
In order to calculate the angle below the horizontal for the velocity of the hockey puck, you need to calculate both x and y component of the velocity of the puck, and also you need to use the following formula:
(1)
θ: angle below he horizontal
vy: y component of the velocity just after the puck hits the ground
vx: x component of the velocity
The x component of the velocity is constant in the complete trajectory and is calculated by using the following formula:
vo: initial velocity = 28.0 m/s
The y component is calculated with the following equation:
(2)
voy: vertical component of the initial velocity = 0m/s
g: gravitational acceleration = 9.8 m/s^2
y: height
You solve the equation (2) for vy and replace the values of the parameters:
Finally, you use the equation (1) to find the angle:
The angle below the horizontal is 12.60°
When a magnet is moved into a coil of wire, changing the magnetic field and magnetic flux through the coil, a voltage will be generated in the coil according to Faraday's Law.
For an individual to reduce his or her carbon footprint, they can:
- Reduce the use of automobile
- switch other renewable energy sources like solar energy
Hydrogen fuels are clean energy sources and should replace fossil fuels.
Carbon footprint should be regulated by law in order to reduce the amount of greenhouse gases.
<h3>What is a carbon footprint?</h3>
A carbon footprint is the measure of the total amount of greenhouse gases that are emitted into the atmosphere each year by an individual.
Greenhouse gases are responsible for global warming.
For an individual to reduce his or her carbon footprint, they can:
- Reduce the use of automobile
- switch other renewable energy sources like solar energy
Hydrogen fuels are able to replace fossil fuels as they are clean energy sources.
An individual's carbon footprint should be regulated by law in order to reduce the amount of greenhouse gases released.
In conclusion, greenhouse gases are responsible for global warming.
